Dish-hashing ll lachines; and I do declare the following to bc a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to make and use the same.

This invention relates to dislnwashing machines, and it has for its object to provide a more simple, durable andlcss'expensive machine of few parts, as compared with the machines now on the market, and with that objoct in view the invention consists in various improvements in the details of construction and arrangement of the parts as will be fully hereinafter described and pointed out in the claims.

In the accompanying drawings forming a part of this specification, Figure 1, is a side elevation of a dish washing machine embodying my invention; Fig. 2, a plan view of the same; Fig. 3, an enlarged perspective view of the casting which forms the casing for the discharge valves; and Fig. 4, a plan view of the bottom of said casting.

Similar letters reler to similar parts through out all the views.

Referring to the drawings A represents the tank of the machine which is cast in one piece and with a central transverse partition B, which "divides the tank into a washing chamber and a rinsing chamber D. The tank is supported by legs E at a suitable distance above the flooring to accommodate the piping etc. arranged on the bottom of the tank. I

A shalt F, extends lengthwise along one side of the tank and is supported in bearings attached to said tank. The shaft F, carries the necessary gearing or a pulley wheel (not shown) at one end for connection with the driving power, as well as a sprocket or pulley wheel (not shown), for connection with a similar wheel (not shown) securedon the shaft (1, which carries, within the Washingchanibcr U, the propeller blades or wheel (not shown), employed in this type or machine for agitating the water and causing a circulation thereof within the tank. The propellers are arranged at the ends of the chambers U and D and are covered by the lids b, which prevent the water being thrown upwardly out of the tank. At the opposite end of the tank a shaft 0 is j0urnaled which carries propeller blades or wheel for the rinsing chamber D, and a sprocket wheel d, which is connected by a chain a, to a similar Wheelfon the shaft F, whereby both propellers may be operated by said shaft F. i

In the bottom of each chamber, C and D, an opening G is formed closely adjacent the dividing partition B, through 'which the chambers may be quickly emptied of their contents. 7 The openings G are covered by the removable perforated plates H, only one of which is shown, through which the water drains, while the escape of tableware or other articles which may have fallen into the chambers is prevented. The plates H are adapted to fit within the openings G and are sup-- ported in place by the lugs g which rest on the edges of the openings.

Secured to the bottom of the tank from underneath so as to extend over and cover the openings G is the casting I, (see Figs. 3 and 4), which forms the casing or chest for the'valves which control the discharge of the water from the chambers. Referring more particularly to Fig. 3, it will be seen that the casting I is formed with two chambers h, the bottoms of which are formed with the flatl'ibs i terminating in the circular flanges surrounding the outlets Z which form bearings or seats j for the valves lz. The arms m of the valves are secured to pins 11., which extend through the bott oms oi the chambers h, and are provided with handles or levers 0, by which the valves may be swung on or off the seats j to close or open thcv outlets Z. The valvesare guided by and ride or slide on the ribs i in their movements and stops p are cast within the chambers h to limit the inward or closing throw of the valves so as to prevent them overlapping the openings or outlets l. The lugs q cast'within the chambers h serve as additional supports for the plates H.

To the bottom of the casting I, a manifold or trap L is cast or secured so as to extend over or cover and connect the outlets 1, whereby the discharge from both.

outlets l will be led into a central chamber L to which is connected a pipe r through which the drainage wator escapes to a sewer or to any other desired place of discharge. In the drawings the chamber L is shown with a joint at each end, one of which is closed bya plug or cap, so that the pipe r may be connected at either end so that the water may be conveyed off in either direction, as found most convenient, without necessitating the use of elbows in connecting the pipe thereto. A pipe 8 leads to the side of the chamber L and empties therein, said pipe being connected to a pipe t, by a T-coupling the branches of which lead to openings formed in the side walls of the tank, near its top, so as to provide overflow openings for the chambers C and D.

Near the bottoms of the chambers (l and. D openings are formed in thewall of the. tank through which are inserted the pipes to, which terminate in the horizon.- tally ext-ending suctional discharge heads M. The pipes w lead froma boiler andfare provided with valves N, whereby the admission of steam to the chambers G and D, for the purpose of maintaining the desired degreeof heat in the water in the chambe'rs, may be controlled. The suction headsM are formed with: vertically extending perforations P at a point near their center of length whereby the water the chambers will be drawn into the heads, by the suction created by the steam in its passage through the same, and .ejeeted therefrom 'atthe ends-oi the heads \vlith the steam. Bythe' use of the heads endenabled to do'away with the coils of pipes heretofore employed in dish washing machines to "keep the waterto the desired degree of hezit; :indgt the same time to more efiectnelly and at considereblleless. expense keep the water as hot as is necessary 6r desirable an to more readily control the degree or heat. I v r -.The chambersare supplied with water through pipes leading. from desired or convenient source-oi suppiy to the opemngs, indicated in broken lines city, in

. the well of the tlank.

I Having thus described my invention what Lclairn as new and desire to secure by Letters Patent is:

1. A dish washing machine having a washing chamber ands rinsing chamber each of which is formed with a bottom discharge opening, a casting extending over said openings formed with outlets, valves for said outlets, and a chamber-common to both of said outlets to receive the discharges therefrom.

2. A dish washing machine having a washing chamber and a rinsing chamber each of which is formed with a bottom discharge opening, a casting having recessed chambers having outlets extending over said discharge openings, valves for said outlets, as chamber to receive the discharge from both outlets, and handles for operating and u rinsing chalfiber each of which is formed with a dissesner charge opening, perforated plates covering said openings,

a casting having recessed, chambers formed with outlets arranged to receive the discharge from both oi. said openlags, valves arranged within said recessed chambers to control the discharge therefrom, handles or levers connected to said valves for operating the some, a chamber arranged to receive the discharge from both of said out lets, and a discharge pipe for said last named chamber.

4. A device for controlling the discharge from adjacent washing and rinsing chambers of a dish Washing tank, comprising a casting having two recessed chambers each hnvlngan outlet, :1 flat rib terminating in a circular ver-' to control said outlets, a pipe for conveying olZE thedlscharge from said last named chamber, overflow openings formed in the walls of said washing and rinsing chambers,

i with outlets arranged to cover said discharge openings, 23,-;

chamber to receive the discharge fromsaid outlets, valves pipes leading therefrom to the last named chamber, and

pipes for supplying said washing and rinsing chambers with water. v

In testimony whereof, I afllx my signature, in presence of two witnesses. 5
